Square Enix today announced the fancy version of Agent 47's continuing stealth saga Hitman: Absolution, called the Professional Edition. The Professional Edition and standard edition are both now available for pre-order at multiple outlets, but with a small catch.

Like so many other publishers and game releases before it, Square Enix is offering different pre-order bonuses to players depending on which retailer they choose to purchase from. Four retailers are offering specific DLC weapon codes with Professional Edition pre-orders, broken down as follows:

Amazon: Bartoli custom pistol, with sight and silencer

Best Buy: Bronson 1928M SMG

GameStop: Agency Kazo TRG sniper rifle

Walmart: Krugermeier 2-2 Pistol with silencer

The Hitman: Absolution Professional Edition itself, regardless of source, includes a hardcover art book and a "making of" video, both of which can give fans further insight into the creation and design of the game. Three high-end in-game weapons also come with the upgraded version of the game: the Agency Jagd P22G pistol, the Agency HX UMP submachine gun, and the Agency SPS 12 semi-automatic shotgun.

As yet, Hitman: Absolution is slated only for a 2012 release, with no clear target date in sight. Participating retailers list the Professional Edition for $79.99, as compared to the standard edition at the standard $59.99.
